APPARATUS FOR FORMING BARRELS OR DRUMS.

Specification of Letters Patent.

Patented Sept. 5, 1905.

Application filed September 12, 1904. Serial No. 224,172.

Be it known that l, Joux L. Sunrram), of Charleston, in the county of Charleston and Stateof South Carolina, have invented certain new and useful Improvements in Apparatus for Forming Barrels or Drums; and [do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in apparatus for forming and constructing barrels or drums, and is designed more particularly for economically constructing the drum disclosed in my Patent No. 697,027, granted to me April 8, 1902. These drums are now made by coiling the sides or body and the three or more outside hoops on a form or core. The shell or body thus formed is then re moved from the :form, and the inner liningho ps,which secure the heads or ends, are then secured in place, after which the heads or ends are inserted and secured by the outside lininghoops.

The object of this invention is to construct the entire drum except the securing of one head in place at one operation; and my invention consists of the parts and combinations of parts, as will be more fully explained, and pointed out in the claims.

In the accompanying drawings, Figure l is a view in side elevation, partly in section, of that portion of the apparatus disclosing my improvements. Fig. 2 is a view in central transverse section of same. Fig. 3 is a view in section of one end of the core or former, showing the latter collapsed, the head-carrier down in its horizontal position, and the drum partly removed.

1 represents a table or frame provided with one or more (one only being shown) shaft-supporting brackets or bearings 2, in which the shaft 3 is journaled. This shaft receives its motion from any suitable source of power and through the intervention of any suitable gearing, or it may be rotated by hand. Mounted on shaft 3 and connected thereto by feather and groove is the sliding hub Jr. This hub is provided at its outer enlarged end with a slot which is engaged by the lever5, which latter is I manipulated to slide the hub longitudinally on I the shaft 3. Pivotally secured to the hub at its inner end is a series of links 6, and pivoted to the hub near its outer end is a series of links 7, each series in the present instance comprising four links; but the number may be increased or decreased, as desired. The links 6 and T of the two series are arranged in pairs, each pair being pivotally secured to and supporting a segmental section 8 of the core or form, the four sections thus combined and related forming when expanded, as shown in Fig. 2, a substantially rigid cylindrical core or form. One edge of each segment or section 8 of the core or form is enlarged, as shown at 9, while the opposite edge 10 carries a thin and, if desired, yielding strip 11, adapted to bridge the spaces between the segments when the latter are expanded and which when the segments are collapsed enter or telescope with the open dovetailed slots 12, formed in the enlarged edge 9 of each segment, and pressing against roller 13 assist in releasing the end of veneer in 12. Located within each slot l2 is a cylindrical rod or roller 13, adapted to engage the end of the veneer at the commencement of the operation, as will be hereinafter described, and hold the same in place during the operation of coiling.

The four segments are enlarged at their ends adjacent to the links 6, and each enlargement is provided with an inwardly-projecting tongue 1%, the free ends of which rest in the groove 15 of collar 16, keyed to the shaft 3, the construction of the parts being such that when the segments are expanded, as shown in Figs. 1 and 2, the tongues is are still within the groove, the latter being sulliciently deep to permit of the collapsing of the segments. This engagement of the tongues 14 on the segments 8 with the groove in the collar 16, fast to the shaft 3, prevents any endwise movement of the segments, but permits of free expanding and collapsing movements due to the sliding of the hub l on the shaft 3. Formed integral with the enlarged ends of the segments 8 are the lipped flanges 17, the lips of which enter sockets 18 in the drumheadcarrier 19 and lock the latter in place when the segments are expanded, as shown in Fig. 1. \Vhen the segmentsare collapsed, the lips of flanges 1? become disengaged from the sockets and permit the drumhead-carrier to be moved away from main portion of the core or form. This drumhezul-carrier 1.) is provided with a hub 20, which latter is journaled in the bearing at the upper end of bracket 21, and the hub 24) of the head-carrier l9 is provided with a centrally-locatcd bore to receive the end of shaft 3. Hence when the parts are assembled as shown in Fig. 1 the shaft 3 is partly supported by the'bracket or bearing 21.

22 is a carriage mounted to slide on table 1 and is propelled back and forth by crank 23 on shaft 24, the latter carrying a pinion meshing with a rack (not shown) on the carriage in the well-known and usual manner. Pivotally secured to this carriage, and hence movable therewith, is the bracket 21, which, as before explained, supports the drumheadcarrier 19. This bracket is of bell -crank shape,and its (normally) horizontal member 25 is provided at its free end with a stud 26, which rests in the slot 27 of the guide 28. This slot is horizontal for part of its length and then curves downwardly, as shown in Fig. 3. From this it will be seen that 'as the carriage is moved away from the form or core the bracket 21 and the drumhead-carrier 19 will be moved therewith, the bracket or bearing and carrier maintaining their vertical positions until the latter clears the shaft 3. As the stud enters the curved portion of the slot the bracket 21 commences to swing downwardly and continues such movement until it and the carrier 19 lie flat upon the carriage, as shown in Fig. 3. The upper face of the carrier is shaped to conform to the seat 28 and opening 29 in the drumhead 30, and when the carrier is in its horizontal position adrumhead 30 is placed thereon, after which the direction of rotation of crank 23 is reversed, thus moving the carriage toward the form or core. At the beginning of this movement of the carriage the bracket 21 begins to rise and after it assumes its vertical position maintains the same until forced in contact with the enlarged ends of the segments 8. After the carrier 19 has been brought to the position last described the segments 8 are expanded by the lever 5 and hub 4, which movement causes the lipped flanges 17 to engage the socketed seats in the carrier 19 and lock the latter solidly and securely to the core or form, so that when the core and carrier so locked are revolved the head necessarily revolves with them.

Located in front of the core or form is the presser-roll 31, mounted on adjustable springarms 32, secured to the table 1. The core or form is provided at its end adjacent to the carrier 19 with a peripheral groove 33 and near its opposite end with the peripheral groove 34, and the carrier 19 is provided on its end adjacent to the core or form with a groove 35. These grooves 33, 34, and 35 are designed to receive three inside hoops of the drum, the hoops resting in grooves 33 and 35 forming seats and locks for the head'30, while the hoop resting in groove 34 forms a seat for the bottom or lower head of the drum.

With the parts assembled as shown in Fig. 1 the end of a strip of veneer is introduced into one of the slots 12 on the front side of the machine adjacentto but under the presser roll 31 The end thus introduced is engaged by the loose clamping-roller 13, which acting as a wedge clamps the veneer in the slot. Before, however, the end of the veneer is locked in the form or core, as above explained, three of the strips to form inner hoops are tacked to the veneer at their upper ends in position toenter the three grooves 33, 34, and 35. Af-

ter the veneer has been locked in the form or core, the latter is rotated by rotating the shaft 3, and the veneer is carried under the presser-roll 31 and under the presser-foot 32, or if a nailing-machine be employed in connection with the former under the toes of the nailing-machine, which toes would occupy about the position the presser 32 occupies when drum is completed and form collapsed.

The veneer can be coiled one or more times around the form or core and is nailed by ma chine or hand to the hoops 37 and also to the head 30, if desired, the nails being upset or clenched on the inside by engagement with the metal segment 8. After the parts-viz, sides,the inner and the outer hoops have been thus secured by nails the segments are collapsed by the endwise movement of the hub and the drumhead-carrier 19 is turned to its horizontal position, thus leaving the completed drum free to be withdrawn from the core or form, as shown in Fig. 3.

After the completed drum thus formed has been stripped or removed from the core or form the bottom head or lower end can be placed in position and secured by nailing the fourth or remaining lining-hoop against the outer face of same and the closure or stopper for the head 30 placed in the latter and temporarily secured against displacement.

It-is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my invention. Hence 1 would have it'understood that I do not wish to confine myself to the exact construction of parts shown and described; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
